It works both ways though. A few days ago on /r/smallbusiness, someone was complaining that he gave away a lot of product and money to "influencers" and didn't get a penny in return. The responses were overwhelmingly telling him that he can't just hand out stuff, he has to tell them what to do with it, where to show it off, how many times to do that, etc. A platform that provided a more structured agreement between the influencers and their clients would go a long way to fixing this, and would help both parties. It's perfectly reasonable to take a fee for doing that.
